WINDOW-SCREEN CONSTRUCTION.

oosen.

To all whom it may concern:

Be it known that I, ALBERT KAMIN, a citizen of the United States, andresident of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in lVindow-ScreenConstruction; and I do hereby declare that the following description ofmy said invention, taken in connection with the accompanying sheet ofdrawings, forms a full, clear, and exact specification, which willenable others skilled in the art to which it appertains to make and usethe same.

This invention has general reference to window screen construction, andit consists, essentially, in the novel and peculiar combination of partsand details of construction, as hereinafter first fully set forth anddescribed, and then pointed out in the claim.

In these drawings, which serve to illustrate this invention more fully,Figure 1 is an elevation of a portion of a window casing fitted wit-h myimproved window screen, and showing the screen in raised position. Fig.2 is a similar View illustrating the screen in lowered position. Fig. 3is a sectional view on line 00 m of Fig. 2. Fig. 4 is fragmental view ofthe catch on said screen. Fig. 5 is an edge or end view of the same.

Like parts are designated by the same characters and symbols ofreference in all the figures.

The object of this'invention is the production of a window screen thatshall be very durable, easily applied to, and removed from, a windowcasing, and that can be applied to existing window screens.

In the drawings the reference letter A designates a window casing, andB, the window screen. As now usually constructed, this window casing hasat both of its inner sides, window or sash stops and upon these stopsnarrow projecting ribs or guides adapted to engage longitudinal groovesat the sides of the window screen. In use, these narrow strips orprojecting ribs are easily and frequently broken, thereby destroying theusefulness of the screen, To avoid this objection, I discard in thepresent construction, these longitudinal strips and fasten, by anysuitable means, to the opposing faces 12, 18, of the window casing A,metallic guards C, l), preferably made from strips of sheet metal, thelongitudinal edges of which are bent at right angles so that theseguards are U-shaped in cross section, the space 14, be-

tween the parallel members 15, 16, of which is slightly wider than thethickness of the screen frame members 17, to permit the screen to moveeasily in these guides or guards C, D. The length of the guards ispreferably somewhat shorter than the height of the screen, and theside-members of said guards, 15, are shorter than the side-members 16,to afford spaces 18, through which the screen may be passed to enableits removal from the window casing when lifted high enough to permit thelower end of the screen to pass through said spaces 18.

Upon the face of one of the side rails 17 of the screen B there ispivoted, preferably by a screw 19, a catch E, having an outwardlyprojecting lug 20, by which said catch may be rotated, a stop pin orother similar means 21, being located above the pivotal screw 19 toprevent the catch E from being lifted higher than necessary. This catch,when the screen is lifted sufficiently high, may be turned upwardly asshown in Fig. 1, so that it may engage the upper edge of the short sidemember of the guard C, and thereby sustain the screen B in raisedposition. When the screen is lifted above the last-- mentioned position,the catch E will auto matically drop (by gravitation) and assume theposition illustrated in Figs. 2 and l, and thereby the window screenbeing lowered to the position shown in Fig. 2.

The guard members C, D, may, in the cheaper construction, be made fromgalvanized sheet iron or steel, and in the more expensive embodiment ofmy invention be made from non-ferric sheet metal, such as copper, brass,bronze, and analogous metals, and finished to correspond with thebuilders hardware of the room or rooms in which the window screens areemployed.

It will be noticed that this invention does not interfere with existingwindow screens having the longitudinal grooves in the side railsthereof, since in my present construction, the window screen is guidedon both sides of these rails, but in new construction of these screensthe cost thereof is slightly reduced by the omission of theselongitudinal grooves, and their durability materially augmented.

Having thus fully described this invention, I claim as new and desire tosecure to me by Letters Patent of the United States- A window screenconstruction, including, in cooperative combination, a window frame,

two oppositely located metallic guards secured to the inner oppositefaces of saidwi'ndew-frame, said guards flaming a substantially U-shapedcross section the parallel members of Which are spaced'apart', one ofsaid parallel members being shorter at its upper end than the coactingparallel 'memshorter parallel member of'sai'd' guards to sustaln sa1dwmdow screen 1n ralsed posl- 171011:

In testimony that I claim the foregoing as 15 my invention, I havehereunto set my hand in the presence of two subscribing Witnesses.
